Guys,
Need some advice.
My car has an issue with fast idle when warm - typically it will sit around 1200 - 1600 rpm if left alone. In order to prevent me sounding like a boy racer, I can reduce the idle by holding the car on the brake and letting the clutch out slowly to reduce the REVs. Once reduced they generally stay low.
Friend put his reader OBD reader onto the car and it reported P0410 Secondary Air Injection System.
I have taken the car to a merc garage for further diagnoses and they advise that its the vacuum pipes at the rear of the supercharger that have perished. Part numbers 01030471, 01030252 and 01020242 (presume any one of these 3).
They have quoted me £1082.46 for this work as apparently the supercharger needs to be removed to access the pipes.
Has anyone had similar or can advise if this is the case.
Many thanks
Andy.
